8. Relationship between pressure and temperature Volume is held constant
Gay-Lussac Law Notes
Relationship between pressure and temperature
Volume is held constant

9. Gay-Lussac’s Law
If the temperature of a gas increases, the pressure also increases
This is a direct relationship between T and P
P1 = P T1 T2

10. Gay-Lussac’s Law __1.00__ 298 _P2_ 318 = P2 = 1.10 atm
Example: If a gas at 25.0ºC and 1.00 atm is heated to 45.0ºC, then what is the new pressure? Assume constant volume
__1.00__
298
_P2_
318 =
P2 = 1.10 atm

11. Gay-Lussac’s Law Practice
Complete the practice problems at your desk. Selected responses will be reviewed as a class.

12. Combined Gas Law Notes

13. Combined Gas Law Put Boyle’s, Charles, and Gay- Lussac’s Laws together
Used when a variable is not held constant
P1V1 = P2V2
T T2

14. Combined Gas Law/Mixed Gas Law Practice
